//
// Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
//
// Solution:
//
// We assume the radius of the polygon is half the size of the canvas at first
// at each index we check if the text overlaps.
//
// Where it does, we store that angle and that index.
//
// After finding the largest index and angle we calculate how much we need to remove
// from the shape radius to move the point inwards by that x.
//
// We average the left and right distances to get the maximum shape radius that can fit in the box
// along with labels.
//
// Once we have that, we can find the centre point for the chart, by taking the x text protrusion
// on each side, removing that from the size, halving it and adding the left x protrusion width.
//
// This will mean we have a shape fitted to the canvas, as large as it can be with the labels
// and position it in the most space efficient manner
//
